There are some situations where a tag can hang around incorrectly even when not tasks have that tag. We are looking into this issue. In the meantime, we have a cleanup program that runs once a day to remove these stray tags, so if you wait 24 hours they should be gone.

It would be helpful if you could let us know how you deleted the tags. Did you remove the tags from the tasks, or did you complete or delete the tasks? Did you use the multi-edit tool, or edit them one-by one? Did you do this via a 3rd party app, or this website?

in my case i still see 3 not used tags (i have not used them for several weeks) only in my android - app "ultimate to do list". i cannot see them on the webpage but it is very annoying that the app still knows of them. should i ask the developer of the android app or is this somewhat related to the problem that is described in this threat?
(and maybe this is a little help for fixing this issue... )

I also have tags, which are not used in any task. When I select that tag, I see that 3 tasks are hidden. Clicking "Turn off filters" does not show any task. Also, when I fetch all tasks with TaskUnifier, there are no tags shown in this client.

As far as I can remember, I had used tags earlier this year (around July and August) and I still had some tasks which had tags associated with them.

But now, I don't see tags at all in the ToodleDo web interface. I had used them at one point when I first started using ToodleDo, but I'd stopped using the ToodleDo web site and android app altogether for a while.

What with New Year's resolutions and all that - to get more organized, etc., and so...

When I came back to ToodleDo earlier this week, I didn't see any tags anywhere anymore in the web interface, even though I believe I have some tasks which still have tags on them. It was a while ago - did I actually remove the tags from my tags and I've forgotten I did so?

I do see them in DGT GTD android app. In fact, in the DGT app, tags are on the same level of importance as contexts, for example. I.e. icon to filter by tags is just as easy to use as the icon to filter by contexts.

Has the main ToodleDo website gotten rid of tags, and DGT GTD android app hasn't caught up yet?
